PENCIL.

. Application filed November 27, 1920. Serial No. 426,836.

ticularly to a novel, cheaply constructed. pencil having many advantagesnot present in those heretofore "suggested. One of the principal objectsof my invention is to provide a pencil which may be very cheaplyconstructed and in'which the operating mechanism is of relativelyextreme simplicity.

A further object is to provide actuating means located in the side ofthepencil as distinguished from in the end. In the latter case muchcomplication results all of which is avoided and ample opportunity isafforded forthe mounting of a lead container and an eraser.

A further object is to so construct the encil body as to provide meanswhereby the ongitudinal axle bending may be formed without the necessityfor longitudinal drilling. In pencils having wood bodies this is asource of great manufacturing ditficulty and it is avoided in myconstruction by very simple means.

The invention will be better understood by reference tothe accompanyingdrawings,

wherein,

. Fig. -1 is a side view of a pencil constructed in accordance with myinvention;

Fig. 2 is an enlarged longitudinal sectional view showing the operatingposition of the parts;

Fig. 3 is a similar view showing the operasing catch in position toa\ivance the lea 2 Fig. 4 is a plan view, and,

Figs. 5 and 6 are sectional views on the lines 55, 6-6, respectively, ofFig. 2.

In thedrawings it will be seen that the pencil includes a body ortion10, which may advantageously be ormed of wood, a metallic point 11, alead container 12, and an eraser 13. In preparing the body for thereception of the operatingparts, I first form a longitudinal saw-cut 14,which is of a depth less than the radius of the body, and a secondsaw-cut 15, located at the axes of the body and of less width than thefirst cut..

The second saw-cut may well be of rectangular cross section and of asizesubstantially fitting a similarly shaped plunger'or rack 16. The rack,as shown in Fig. 2, is provided with teeth or serrations 17 on its uppersur face adapted to be engaged by a resilient pawl 18, secured at 18, toan arm. 20. The arm is pivoted to a retaining member 19, of U-shape incross section, the pin 18* serving as a pivot for the arm. The arm isprowhich fit snugly between the upstanding sides of themember 19. Thebody may be cut away atf22, to permit of engagement of the finger nailwith the point 23 of the arm.

It will be seen that the bottom-portion of the U-shaped member underliesthe plunger 16 and that when the plunger is in place the arm andattached pawl cannot be removed. The saw-cut 14 is filled by suitablestrips 24, the outer surfaces of which. conform to the I outline of thepencilbody. A space is left at awl vided with depending side members 21,

upwardly on the rack. Upon pressing the arm the plunger is advancedcorrespondingly. If it is desired to retract the plunger or to disengageit from the actuating mechanism,th'e arm is swung upwardly to an extentsufiicient to disen go the pawl from the rack. Upon removing thethreaded tip Thereafter the actuating mechanismmay be easily removed. av

I claim: 1. In a pencil, the combination of a body having a longitudinalaxial opening, a rack 11, the plunger will drop of itsown. weight.

adapted to function as a plunger mounted in the opening, a U.-shapedpawl-support mounted in the side of the body, and a pawl pivoted insaidsupport and adapted to engage the rack to effect the advance thereof.

2. In combination a pencil body having a longitudinal axial opening anda side opening'communicating with the axial opening a toothed plungermounted in the axi opening, a U-shaped member mounted in the sideopening, and a spring-actuated pawl mounted. on said U-shaped member andadapted to effect the advance'of the plunger. 3. In combination a pencilbody having an axial opening and a side opening at a point substantiallymidway between the ends of the pencil, a rack mounted in the axialopening, a retaining member mounted in the side opening and having aportion underlying said rack, and a spring-actuated pawl mounted on saidretaining member and adapted to elfect the advance of the rack.

4. In combination a pencil body having an axial opening and a sideopening at a point substantially midway between the ends of the pencil,a rack mounted in the axial opening, a retaining member mounted in theside opening and having a portion under lying said rack, and aspring-actuated pawl mounted on said retaining member and adapted toeffect the advance of the rack, the retaining member and pawl being heldin the side opening solely by the rack.

5. In a pencil, the combination of a body having an axial opening and aside opening V shaped member and adapted to oscillate incommunicatingtherewith, a rack mounted in the axial opening, a 'U-shaped membermounted in the side opening and adapted to underlie the rack, an armpivoted to the U- an'arc outside of the limits of the pencil body, and aspring-actuated finger movable I with the arm. and adapted to engage therack to effect the advance thereof.

6. In a pencil, the combination with the body thereof, of meansincluding a plunger for actuating a lead, said body being. promemes;

ed normally to lie flush with the body, and

tension means carried by the lever adjacent its pivoted end adapted witheach swinging movement of the lever to engage the plunger to propel thesame longitudinally through the pencil, substantiallyas described.

8. In combination with a pencil, a toothed plunger, means forguiding theplunger and a lead in advance thereof in longitudinal movements throughthe pencil, and ,means for propelling the plunger comprising a pivotedelement having spring means adapted for resilient engagement with theplunger teeth, said means being moved lengthwise of the pencil with eachoscillation of the element to thereby propel the plunger, lon t udinallyof the pencil, substantially. as 5 scribed.
